MACHINE FOR WRAPPING T IRE TAPE OR LIKE.

Application filed January This invention has to do with a machine for placing tin" foil covers about rolls of frictional-fabric or tire tape, although its use is not so restricted, but may be extended as found practicable. Heretofore, to my knowledge, the application of this cover has been entirely by hand, and it is the purpose of the present invention to devise a machine for displacing the hand operation.

The machine has particularly to do with the.

folding of the edges of the cover over the The machine operates more rapidly and satisfactorily than the hand operation.

In the drawings there is shown one form of the invention, it being understood that other forms may be adopted within the spirit and scope of the appended claims.

In the drawings: Figure 1 is a'side elevation of the machine;

Figure 2 is an end view; liigure 3 is a roll of tire tape, uncovered; an

Figure 4 is a covered roll such as produced by the machine.

The machine comprises a table or platforml, the upper surface of which is removed along a given line to accommodate a belt 2 which is supported on pulleys 3 and 4 so that its upper run is substantially flush with the top of the table. The belt is driven at suitable speed from a motor '5, having a reduction gearing 6 and clutch 7 controlled by a foot lever 8. A sprocket 9 connected to the clutch and the pulley 4 serves to drive the At the-sides of the belt are arranged upright posts 10; on which is loosely mounted and guided an inverted channel 11, which may be weightedif desired andprovided at one end with guidingfianges 12 which may be spring pressed as shown at 12 Adjustable collars 13 are supported upon the posts to limit the downward movement of the channel, this provision being necessary to enable the machine to operate upon rolls of different sizes.

Parallel to the belt are'folding or crimping bars or rolls 14. These are long rollers spaced apart a distance slightly greater than -the width of the roll and are round bars tapered at the front end as at 15. The front end of each bar is adjusta'bly supported in a standard 16 near the front end of the belt the wrapper to fold it progressively from the 2c, 1924. Serial No. 388,690.

and the rear end of the bar is pivotally supported in a short standard 1.7 near the end of the belt. As shown, the bar is inclined relative to the belt so that at the entrance to the machine it will be located near the outer periphery of the tape roll. In this manner, the pro ecting edges of the tin foil are attached at the edge of the rolland gradually shaped down over the surface of the roll as the roll. is moved forwardly by the belt.

At the far end of the table the roll of tape with 'the tin foil roughly shaped about it, is

passed into a chute 18, at the lower end of which are located two pressing or finishingrolls 19. These rolls are journaled on the upper ends of levers 20 which are pivoted at 21 on an apron 22, in front of the machine.

The rollsare rotatedfrom the shaftof the 26 in Figure 2. The levers.20 are forced apart at their lower ends, which presses the rolls 19 together by a link 27 on the ends of which'are mounted springs 28 which exert the yielding pressure required.

In the operation of the machine, the operative rolls the tire tape in a layer of tin foil so that the edges of the foil project 6utward- 1y of the roll. He then feeds the roll onto the belt and beneath the presser bar 11.

The belt rolls the tire tape forwardly and the side rolls 14 give it a preliminary shaping against the side of the roll. As it drops through the chute 18, the rolls 19 give the tin foil a final pressing.

It is obvious that the invention is not limited to strict conformance 'with the showingmade herein, but may be varied and modified as required; nor is it limited to wrapplng t e tape, or to. the use of tin foil, audit may be more widely adapted'if desired. An
